FIG. 2 is a conceptual perspective view of a cutting apparatus provided with a foreign substance removing function according to a first embodiment of the present invention, and FIG. 3 is a conceptual sectional view thereof.

Referring to FIGS. 2 and 3, the cutting apparatus provided with the foreign substance removing function according to the first embodiment of the present invention includes a cutter 20, an inlet 31, and an injection port 41.

The cutter 20 performs a function of cutting the cutting body 10.

For example, the cutter 20 may be a linear motion cutter 20 that cuts the cut 10 by linear motion. More specifically, although not shown in the drawing in order not to obscure the gist of the present invention, the movement of the cutter 20 can be controlled by the conveying means, for example, y, z axis directions. That is, the cutter 20 moves in the x, y, and z axis directions under the control of the feeding means, moves to the initial cutting point, and then linearly moves along the cutting direction to cut the cut body 10 . At the end of the cutter 20, which is a point of contact with the cutting body 10, a cutting material such as diamond, for example, may be provided.

For example, the cutting target 10 to be cut may be a touch sensor, a display panel, a solar cell, and the like, but the cutting target is not limited thereto.

The suction port 31 shares at least a part of the outer circumferential surface of the cutter 20 and sucks and discharges the foreign substances generated in the cutting process of the cut unit 10 by the cutter 20. [

More specifically, during the cutting and cutting process of the cutting unit 10, a foreign substance such as a cutting powder or the like is inevitably generated from the cutting unit 10, and the foreign matter is cut along the cutting line 10 And is attached to the outer circumferential surface of the cutter 20. Such foreign matter must be removed because it causes defects in the subsequent process to the cutting unit 10 and contaminates the cutting unit 10 and acts as a factor to lower the characteristics required for the cutting unit 10. [

According to the conventional technique described with reference to FIG. 1, foreign matter accumulated along the cutting line is removed to some extent, but foreign materials adhering to the outer circumferential surface of the cutting machine can not be removed at all. Therefore, during the cutting process, And the process of cleaning the outer surface of the cutter had to be additionally performed. According to the related art, there is a problem that the time required for the entire cutting process is significantly increased due to the cleaning process for the outer circumferential surface of the cutter, and the process efficiency is greatly deteriorated.

On the other hand, according to the first embodiment of the present invention, since the suction port 31 shares at least a part of the outer circumferential surface of the cutter 20, not only the foreign matter accumulated in the cut-off body 10 can be removed, Foreign matter adhering to the outer peripheral surface of the cutter 20 can also be effectively removed.

For example, the suction port 31 may be provided on one side of the cutter 20, that is, on the side where the jetting port 41 is provided.

For example, at least a part of the outer circumferential surface of the cutter 20 shared by the suction port 31 may be provided with a surface roughness reducing coating layer 21 that facilitates generation of airflow including foreign matter and guide air. Since the surface roughness reducing coating layer 21 lowers the surface roughness of the outer circumferential surface of the cutter 20 constituting the suction port 31, the air current composed of the foreign matter and the guide air is smoothly discharged without resistance, The foreign matter adhering to the outer peripheral surface of the cutter 20 can be prevented.

For example, the surface roughness of the surface roughness reducing coating layer 21 may be 0.025 to 6.3 μm based on the arithmetic average roughness (Ra), 0.1 to 25 μm based on the maximum height roughness Ry, May be 0.1 to 25 占 퐉 based on Rz. With this configuration, the airflow including the foreign matter and the guide air is smoothly discharged without being resisted through the surface of the surface roughness reducing coating layer 21, and foreign matter contained in the airflow is adhered to the outer peripheral surface of the cutter 20 The problem can be prevented.

The first distance D1 between the lower end of the suction port 31 and the body 10 is equal to the distance between the jet opening 41 and the cut- May be configured to be larger than the second separation distance (D2), which is a separation distance from the first separation distance (10). With this configuration, it is possible to solve the problem that the guide air is blocked at the lower end portion of the suction port 31 in the process of being sprayed onto foreign objects on the digging assembly 10, and at the same time, It is possible to prevent a phenomenon that the light is reflected from the cutter 20 and leaks to the outside of the ejection opening 41 to contaminate the body 10.

The jetting port (41) serves as a passage through which guide air for guiding foreign matter to the suction port (31) is jetted.

For example, at least one lower region of the suction port 31 and the jetting port 41 may be configured to be bent toward the end of the cutter 20 contacting the cut body 10. With this configuration, the guide air can be precisely jetted toward the foreign object to be removed, and the airflow made of the foreign matter and the guide air can be effectively guided to the suction port 31.

For example, the jetting port 41 may be configured to share at least a part of the outer circumferential surface of the suction port 31. With this configuration, the injection port 41 and the suction port 31 can be integrally formed, so that the configuration of the cutting apparatus can be simplified and the manufacturing cost of the apparatus can be reduced.

For example, the jetting ports 41 may be provided on at least one side or both sides of the cutter 20.

Although the drawings illustrating various embodiments of the present invention are shown as being provided only on one side of the cutter, this is only an exemplary representation. In other words, in the various embodiments of the present invention, the ejection orifice is provided only on one side of the cutter, thereby simplifying the structure of the apparatus or providing the ejection openings on both sides of the cutter.

Referring to FIG. 4, the injection port 42 is physically separated from the suction port 31 to have an independent structure. With this configuration, the degree of freedom in designing the jetting port 42 and the suction port 31 constituting the cutting device is enhanced.

Except for this configuration, the configuration of the modified embodiment is substantially the same as that of the first embodiment described in detail above, and therefore, a duplicate description will be omitted.

The cutter 20 performs a function of cutting the cutting body 10.

For example, the cutter 20 may be a linear motion cutter 20 that cuts the cut 10 by linear motion. More specifically, although not shown in the drawing in order not to obscure the gist of the present invention, the movement of the cutter 20 can be controlled by the conveying means, for example, y, z axis directions. That is, the cutter 20 moves in the x, y, and z axis directions under the control of the feeding means, moves to the initial cutting point, and then linearly moves along the cutting direction to cut the cut body 10 . At the end of the cutter 20, which is a point of contact with the cutting body 10, a cutting material such as diamond, for example, may be provided.

For example, the cutting target 10 to be cut may be a touch sensor, a display panel, a solar cell, and the like, but the cutting target is not limited thereto.

The first suction port 31 and the second suction port 32 share at least a part of the outer circumferential surfaces on both sides of the cutter 20 and suck foreign matters generated in the cutting process of the cutting unit 10 by the cutter 20, .

Such foreign matter must be removed because it causes defects in the subsequent process to the cutting unit 10 and contaminates the cutting unit 10 and acts as a factor to lower the characteristics required for the cutting unit 10. [

According to the conventional technique described with reference to FIG. 1, foreign matter accumulated along the cutting line is removed to some extent, but foreign materials adhering to the outer circumferential surface of the cutting machine can not be removed at all. Therefore, during the cutting process, And the process of cleaning the outer surface of the cutter had to be additionally performed. According to the related art, there is a problem that the time required for the entire cutting process is significantly increased due to the cleaning process for the outer circumferential surface of the cutter, and the process efficiency is greatly deteriorated.

According to the second embodiment of the present invention, since the first suction port 31 and the second suction port 32 share at least a part of the outer circumferential surfaces on both sides of the cutter 20, the foreign substances accumulated in the cut- At the same time, foreign substances adhered to the outer peripheral surfaces on both sides of the cutter 20 can be effectively removed.

For example, the first suction port 31 is provided on one side of the cutter 20, that is, on the side where the jetting port 41 is provided, and the second suction port 32 is provided on the other side of the cutter 20, And may be provided on the opposite side of the side where the jetting port 41 is provided.

For example, a first surface roughness reducing coating layer 21 is formed on at least a part of the outer circumferential surface of the cutter 20 shared by the first suction port 31, and a cutter 20 The first surface roughness reducing coating layer 21 and the second surface roughness reducing coating layer 22 may be formed on at least a part of the outer circumferential surface of the first surface roughness reducing coating layer 22 and the second surface roughness reducing coating layer 22, Lt; / RTI > The first surface roughness reducing coating layer 21 lowers the surface roughness of the outer circumferential surface of the cutter 20 constituting the first suction port 31 while the second surface roughness reducing coating layer 22 lowers the surface roughness of the second suction port 32 constituting the second suction port 32 The surface roughness of the outer circumferential surface of the cutter 20 is lowered so that the airflow made of the foreign matter and the guide air is smoothly discharged without resistance and the foreign matter contained in the airflow is adhered to the outer circumferential surface of the cutter 20 .

For example, the surface roughnesses of the first surface roughness reducing coating layer 21 and the second surface roughness reducing coating layer 22 may be 0.025 to 6.3 μm based on the arithmetic average roughness (Ra), or the maximum roughness Ry And may be 0.1 to 25 占 퐉 or 0.1 to 25 占 퐉 based on the ten-point average roughness (Rz). With this configuration, the airflow including the foreign matter and the guide air is smoothly discharged through the surfaces of the first surface roughness reducing coating layer 21 and the second surface roughness reducing coating layer 22 without resistance, The foreign matter adhering to the outer peripheral surface of the cutter 20 can be prevented.

For example, the first suction port 31 is provided on one side of the cutter 20, the second suction port 32 is provided on the other side of the cutter 20, and the jet port 41 is provided on the side of the first suction port 31 And may share at least a part of the outer circumferential surface. With this configuration, the jetting port 41, the first suction port 31, and the second suction port 32 can be integrally formed, so that the configuration of the cutting device can be simplified and the manufacturing cost of the apparatus can be reduced.

For example, the first distance D1 between the lower end of the first suction port 31 and the body 10 is the second distance D2, which is the distance between the jetting port 41 and the body 10 to be drawn. ). ≪ / RTI > With this configuration, it is possible to solve the problem that the guide air is blocked at the lower end portion of the suction port in the process of being sprayed onto foreign matter on the digging assembly 10, and the airflow made of the foreign matter and the guide air is not guided to the suction port, It is possible to prevent a phenomenon that the ejected droplets are reflected from the ejection port 41 and leaks to the outside of the ejection opening 41 to contaminate the drawn group 10.

FIG. 7 is a conceptual sectional view of a cutting apparatus provided with a foreign matter removing function according to a modified embodiment of the second embodiment of the present invention.

Referring to FIG. 7, the injection port 42 is physically separated from the first suction port 31 to have an independent structure. With this configuration, the degree of freedom in designing the jetting port 42 and the first suction port 31 constituting the cutting device is enhanced.

Except for this configuration, the configuration of the modified embodiment is substantially the same as that of the second embodiment described above in detail, and thus a duplicate description will be omitted.

FIG. 8 is a conceptual perspective view of a cutting apparatus having a foreign substance removing function according to a third embodiment of the present invention, and FIG. 9 is a conceptual sectional view thereof.

Referring to FIGS. 8 and 9, a cutting apparatus having a foreign substance removing function according to a third embodiment of the present invention includes a cutter 200, an air inlet 301, and a jetting port 401.

The cutter 200 performs a function of cutting the cutting body 10.

For example, the cutter 200 may be a rotary cutter 200 that cuts the cut 10 by rotation. In this case, the cutter 200 has a blade for cutting And may have a disc shape formed thereon. In order not to obscure the gist of the present invention, in order to prevent the gist of the present invention from being overshadowed, in this case, in order to rotate the cutter 200, a cutter 200, that is, a rotating shaft passing through the center of the original plate, Or the like may be additionally provided. The movement of the cutter 200 can also be controlled by the conveying means, for example, the direction of movement can be in the x, y, z axis direction with respect to the three-dimensional coordinate system. That is, the cutter 200 moves in the x, y, and z axis directions under the control of the feeding means, moves to the initial cutting point, and rotates along the cutting direction to cut the cut body 10 . The end of the cutter 200, which is the point of contact with the cutting body 10, that is, the blade, may be provided with a cutting material such as diamond or the like.

For example, the cutting target 10 to be cut may be a touch sensor, a display panel, a solar cell, and the like, but the cutting target is not limited thereto.

The suction port 301 shares at least a part of the outer circumferential surface of the cutter 200 and sucks and discharges the foreign substance generated in the cutting process of the cut unit 10 by the cutter 200.

More specifically, in the process of cutting and cutting the cutting unit 10 by the cutting unit 200, foreign matter such as cutting powder or the like is inevitably generated from the cutting unit 10, and the foreign matter is cut along the cutting line 10 And is attached to the outer circumferential surface of the cutter 200. Such foreign matter must be removed because it causes defects in the subsequent process to the cutting unit 10 and contaminates the cutting unit 10 and acts as a factor to lower the characteristics required for the cutting unit 10. [

According to the conventional technique described with reference to FIG. 1, foreign matter accumulated along the cutting line is removed to some extent, but foreign materials adhering to the outer circumferential surface of the cutting machine can not be removed at all. Therefore, during the cutting process, And the process of cleaning the outer surface of the cutter had to be additionally performed. According to the related art, there is a problem that the time required for the entire cutting process is significantly increased due to the cleaning process for the outer circumferential surface of the cutter, and the process efficiency is greatly deteriorated.

On the other hand, according to the third embodiment of the present invention, since the suction port 301 shares at least a part of the outer circumferential surface of the cutter 200, it is possible not only to remove the foreign substances accumulated in the cut-off body 10, Foreign matter adhering to the outer peripheral surface of the cutter 200 can also be effectively removed.

For example, the suction port 301 may be provided on one side of the cutter 200, that is, on the side where the jetting port 401 is installed. Also, since the rotary motion cutter 200 has to be rotated for cutting, the suction port 301 must be fixed, so that the cutter 200 and the suction port 301 are configured to be finely spaced.

For example, at least a part of the outer circumferential surface of the cutter 200 shared by the suction port 301 may be provided with a surface roughness reducing coating layer 21 that facilitates generation of airflow including foreign matter and guide air. Since the surface roughness reducing coating layer 21 lowers the surface roughness of the suction port 301, the airflow made of the foreign matter and the guide air is smoothly discharged without resistance, and foreign matter contained in the airflow is discharged to the outer peripheral surface Can be prevented.

The suction port 301 is provided at one side of the cutter 200 and the first separation distance D1 which is the distance between the lower end of the suction port 301 and the work 10 is shorter than the jet port 401, May be configured to be larger than the second separation distance (D2), which is a separation distance from the first separation distance (10). With this configuration, it is possible to solve the problem that the guide air is blocked by the lower end portion of the suction port 301 in the process of being sprayed by the foreign substance on the digging assembly 10, and the airflow made of the foreign matter and the guide air is guided to the suction port 301 It is possible to prevent a phenomenon in which the light is reflected from the cutter 200 and leaks to the outside of the jetting port 401 to contaminate the body 10.

The jetting port (401) functions as a passage through which guide air for guiding foreign matter to the suction port (301) is jetted.

For example, at least one lower region of the suction port 301 and the jetting port 401 may be configured to be bent toward the end of the cutter 200 contacting the cut body 10. With this configuration, the guide air can be accurately jetted toward the foreign object to be removed, and the airflow made of the foreign matter and the guide air can be effectively guided to the suction port 301.

For example, the jetting port 401 may be configured to share at least a part of the outer circumferential surface of the suction port 301. With this configuration, the injection port 401 and the suction port 301 can be integrally formed, so that the configuration of the cutting apparatus can be simplified and the manufacturing cost of the apparatus can be reduced.

10 to 12 are views showing examples of the configurations of the inlet 301 and the injection port 401 which can be applied to the third embodiment of the present invention and the forth embodiment to be described later. The configuration of the suction port 301 and the jetting port 401 disclosed in Figs. 10 to 12 is suitable when the cutter 200 is a rotary type, but is not limited thereto, and is also applicable to a linear motion type.

10, the width W1 of the suction port 301 provided at one side of the cutter 200 may be smaller than the diameter D of the cutter 200, and the width W1 of the suction port 301 may be set to be smaller than the diameter D of the cutter 200. [ And the first distance D1 between the lower end of the suction port 301 and the workpiece 10 may be larger than or equal to the width W2 of the jetting port 401, May be larger than the second separation distance (D2), which is a separation distance from the group (10). With this configuration, it is possible to prevent the guide air injected through the injection port 401 from leaking to the other side of the cutter 200 together with foreign matter, and the airflow including the foreign matter and the guide air can be guided to the lower part of the cutter 200 So that it can be easily guided to the suction port 301 and discharged to the outside.

FIG. 13 is a conceptual sectional view of a cutting apparatus equipped with a foreign substance removing function according to a modified embodiment of the third embodiment of the present invention.

Referring to FIG. 13, the jetting port 401 is physically separated from the suction port 301 to have an independent structure. With such a configuration, the degree of freedom in designing the injection port 401 and the suction port 301 constituting the cutting apparatus is enhanced.

Except for this configuration, the configuration of the modified embodiment is substantially the same as that of the third embodiment described above in detail, and therefore, a duplicate description will be omitted.

FIG. 14 is a conceptual perspective view of a cutting apparatus equipped with a foreign substance removing function according to a fourth embodiment of the present invention, and FIG. 15 is a conceptual sectional view thereof.

14 and 15, a cutting apparatus equipped with a foreign substance removing function according to a fourth embodiment of the present invention includes a cutter 200, a first suction port 301, a second suction port 302, .

The cutter 200 performs a function of cutting the cutting body 10.

For example, the cutter 200 may be a rotary cutter 200 that cuts the cut 10 by rotation. In this case, the cutter 200 has a blade for cutting And may have a disc shape formed thereon. In order not to obscure the gist of the present invention, in order to prevent the gist of the present invention from being overshadowed, in this case, in order to rotate the cutter 200, a cutter 200, that is, a rotating shaft passing through the center of the original plate, Or the like may be additionally provided. The movement of the cutter 200 can also be controlled by the conveying means, for example, the direction of movement can be in the x, y, z axis direction with respect to the three-dimensional coordinate system. That is, the cutter 200 moves in the x, y, and z axis directions under the control of the feeding means, moves to the initial cutting point, and rotates along the cutting direction to cut the cut body 10 . The end of the cutter 200, which is the point of contact with the cutting body 10, that is, the blade, may be provided with a cutting material such as diamond or the like.

For example, the cutting target 10 to be cut may be a touch sensor, a display panel, a solar cell, and the like, but the cutting target is not limited thereto.

The first suction port 301 and the second suction port 302 share at least a part of the outer circumferential surfaces on both sides of the cutter 200 and suck foreign substances generated in the cutting process of the cutting unit 10 by the cutter 200, .

More specifically, in the process of cutting and cutting the cutting unit 10 by the cutting unit 200, foreign matter such as cutting powder or the like is inevitably generated from the cutting unit 10, and the foreign matter is cut along the cutting line 10 And is attached to the outer circumferential surface of the cutter 200. Such foreign matter must be removed because it causes defects in the subsequent process to the cutting unit 10 and contaminates the cutting unit 10 and acts as a factor to lower the characteristics required for the cutting unit 10. [

According to the conventional technique described with reference to FIG. 1, foreign matter accumulated along the cutting line is removed to some extent, but foreign materials adhering to the outer circumferential surface of the cutting machine can not be removed at all. Therefore, during the cutting process, And the process of washing the outer surface of the cutter 200 had to be additionally performed. According to the related art, there is a problem that the time required for the entire cutting process is significantly increased due to the cleaning process for the outer circumferential surface of the cutter, and the process efficiency is greatly deteriorated.

According to the fourth embodiment of the present invention, since the first suction port 301 and the second suction port 302 share at least a part of the outer circumferential surfaces on both sides of the cutter 200, the foreign substances accumulated in the cut- At the same time, foreign matter adhering to the outer circumferential surfaces on both sides of the cutter 200 can be effectively removed.

For example, the first suction port 301 is provided on one side of the cutter 200, that is, on the side where the jetting port 401 is installed, and the second suction port 302 is provided on the other side of the cutter 200, And may be provided on the opposite side of the side where the jetting ports 401 are installed. Since the first suction port 301 and the second suction port 302 are fixed, the rotary cutter 200 must be rotated for cutting, and the cutter 200, the first suction port 301, The first suction port 200 and the second suction port 302 are configured to be finely spaced.

For example, a first surface roughness reducing coating layer 201 is formed on at least a part of the outer circumferential surface of the cutter 200 shared by the first suction port 301, and a cutter 200 The first surface roughness reducing coating layer 201 and the second surface roughness reducing coating layer 202 may be formed on at least a part of the outer circumferential surface of the first surface roughness reducing coating layer 202 and the second surface roughness reducing coating layer 202, Lt; / RTI > The first surface roughness reducing coating layer 201 lowers the surface roughness of the outer circumferential surface of the cutter 200 constituting the first suction port 301 while the second surface roughness reducing coating layer 202 lowers the surface roughness of the outer surface of the cutter 200 constituting the second suction port 302 The surface roughness of the outer circumferential surface of the cutter 200 is lowered so that the airflow made of the foreign matter and the guide air is smoothly discharged without resistance and the foreign matter contained in the airflow is adhered to the outer circumferential surface of the cutter 200 .

For example, the first suction port 301 is provided on one side of the cutter 200, the second suction port 302 is provided on the other side of the cutter 200, and the jet port 401 is provided on the side of the first suction port 301 And may share at least a part of the outer circumferential surface. With this configuration, the injection port 401, the first suction port 301, and the second suction port 302 can be integrally formed, so that the configuration of the cutting apparatus can be simplified and the manufacturing cost of the apparatus can be reduced.

For example, the first distance D1 between the lower end of the first suction port 301 and the body 10 is the second distance D2, which is the distance between the jetting port 401 and the body 10 to be drawn. ). ≪ / RTI > This configuration can solve the problem that the guide air is blocked at the lower end of the suction port in the process of being sprayed by the foreign substance on the digged body 10 and that the airflow made of the foreign matter and the guide air is not guided to the suction port, It is possible to prevent a phenomenon that the ejected droplets are reflected from the ejection port 401 and leaks to the outside of the ejection port 401 and contaminates the drawn group 10.

For example, the third distance D3, which is the distance between the lower end of the second suction port 302 and the workpiece 10, may be smaller than the first distance D1 or the first distance D1 ). ≪ / RTI > The foreign matter generated on one side of the cutter 200 and moved to the other side of the cutter 200 along with the guide air and foreign matter generated on the other side of the cutter 200 leaks to the outside of the second suction port 302 But is effectively guided to the second suction port 302 and discharged.

The jetting port 401 functions as a path through which guide air is guided to guide the foreign matter to the first suction port 301 and the second suction port 302.

For example, at least one lower region of the first suction port 301, the second suction port 302, and the jetting port 401 may be configured to be bent toward the end of the cutter 200 contacting the cut- have. With this configuration, the guide air can be accurately jetted toward the foreign object to be removed, and the airflow made of the foreign matter and the guide air can be effectively guided to the first suction port 301 and the second suction port 302.

16 is a conceptual sectional view of a cutting apparatus equipped with a foreign matter removing function according to a modified embodiment of the second embodiment of the present invention.

Referring to FIG. 16, the injection port 402 is physically separated from the first suction port 301 to have an independent structure. With this configuration, the degree of freedom in designing the jetting port 402 and the first suction port 301 constituting the cutting device is enhanced.

Except for this configuration, the configuration of the modified embodiment is substantially the same as that of the third embodiment described above in detail, and therefore, a duplicate description will be omitted.

There is an effect of providing a cutting device equipped with a foreign substance discharging structure that can effectively remove foreign substances generated in a process of cutting a cutting object such as a touch sensor, a polarizing plate, various display panels, and the like.

Further, there is an effect that the phenomenon that the foreign substance adheres to the surface of the cutter can be prevented.
